What Is Heel Discomfort

Plantar Fasciitis

Plantar Fascia

Overview

Plantar fasciitis is a painful inflammatory process of the plantar fascia, a thick fibrous band of connective tissue originating on the bottom surface of the calcaneus (heel bone) and extending along the sole of the foot towards the five toes. Pain in the arch or heel often indicates inflammation of the long band of tissue under the foot (the plantar fascia). It can cause sharp pain and discomfort in either the mid arch region or at the inside heel, and less commonly the outside heel. It frequently causes pain upon rising from rest (especially first thing in the morning) and can progress to agony by the end of the day. Although plantar fasciitis is the most common cause of this pain, it must be skilfully differentially diagnosed from other conditions via a thorough history taking and physical examination.


Causes

Plantar fasciitis is caused by drastic or sudden increases in mileage, poor foot structure, and inappropriate running shoes, which can overload the plantar fascia, the connective tissue that runs from the heel to the base of the toes. The plantar fascia may look like a series of fat rubber bands, but it’s made of collagen, a rigid protein that’s not very stretchy. The stress of overuse, overpronation, or overused shoes can rip tiny tears in it, causing pain and inflammation, a.k.a. plantar fasciitis.


Symptoms

People with this condition sometimes describe the feeling as a hot, sharp sensation in the heel. You usually notice the pain first thing in the morning when you stand. After walking for a period of time, the pain usually lessens or even disappears. However, sharp pain in the center of the heel may return after resting for a period of time and then resuming activity.


Diagnosis

Diagnosis of plantar fasciitis is based on a medical history, the nature of symptoms, and the presence of localised tenderness in the heel. X-rays may be recommended to rule out other causes for the symptoms, such as bone fracture and to check for evidence of heel spurs. Blood tests may also be recommended.


Non Surgical Treatment

About 90% of plantar fasciitis cases are self-limited and will improve within six months with conservative treatment and within a year regardless of treatment. Many treatments have been proposed for the treatment of plantar fasciitis. First-line conservative approaches include rest, heat, ice, calf-strengthening exercises, techniques to stretch the calf muscles, achilles tendon, and plantar fascia, weight reduction in the overweight or obese, and nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen. NSAIDs are commonly used to treat plantar fasciitis, but fail to resolve the pain in 20% of people. Extracorporeal shockwave therapy (ESWT) is an effective treatment modality for plantar fasciitis pain unresponsive to conservative nonsurgical measures for at least three months. Corticosteroid injections are sometimes used for cases of plantar fasciitis refractory to more conservative measures. The injections may be an effective modality for short-term pain relief up to one month, but studies failed to show effective pain relief after three months. Notable risks of corticosteroid injections for plantar fasciitis include plantar fascia rupture, skin infection, nerve or muscle injury, or atrophy of the plantar fat pad. Custom orthotic devices have been demonstrated as an effective method to reduce plantar fasciitis pain for up to 12 weeks. Night splints for 1-3 months are used to relieve plantar fasciitis pain that has persisted for six months. The night splints are designed to position and maintain the ankle in a neutral position thereby passively stretching the calf and plantar fascia overnight during sleep. Other treatment approaches may include supportive footwear, arch taping, and physical therapy.

Surgical Treatment

Surgery is rarely needed in the treatment of plantar fasciitis. The vast majority of patients diagnosed with plantar fasciitis will recover given ample time. With some basic treatment steps, well over 90% of patients will achieve full recovery from symptoms of plantar fasciitis within one year of the onset of treatment. Simple treatments include anti-inflammatory medication, shoe inserts, and stretching exercises. In patients where a good effort with these treatments fails to provide adequate relief, some more aggressive treatments may be attempted. These include cortisone injections or extracorporeal shock wave treatments.


Prevention

Do your best to maintain healthy weight. Plantar fasciitis is caused by wear and tear on your feet. Being overweight drastically increases the pounding your feet take every day. Even losing a few pounds can help reduce heel pain. Avoid jobs that require walking or standing for long periods of time. Having your body weight on your feet all day puts a lot of pressure on your plantar fascia tissue. Replace your shoes on a regular basis. Buy new shoes when the old ones are worn-out. Make sure your shoes will fit your foot size comfortably at the end of the day. Pay attention to the width as well as the length. Use good supportive shoes that will help you with your original problem like arch support, motion control, stability, cushioning etc. Stretch regularly as part of your daily routine. There are a few special stretching techniques for the prevention. Choose soft surfaces for your exercise routine to walk, jog or run on. Rest and elevate your feet every chance you have. Strengthen your foot muscles as part of your exercise routine. Strong foot muscles provide a good support to the plantar fascia. Change your shoes during the work week. Don’t wear the same pair of shoes every day. Perform Warm up exercises such as a short period of walking, a light jog or other easy movement and then stretch before starting the main exercise. Try to avoid dramatic changes in your exercise routine. Increase your exercise level gradually. Don’t run long distance if you are used to walk. Make the change slowly and gradually. Pay attention to your foot pain, do not ignore it. Visit your doctor if the pain continues. Avoid the activities that cause you pain. Use over-the-counter Orthotics or inserts that your doctor may prescribe. Off-the-shelf or custom-fitted arch supports (orthotics) will help distribute pressure to your feet more evenly. Try to avoid barefoot walking, since it may add stress on the plantar fascia ligament.
